摘要：
A method for easily, quickly and accurately detecting a cross leak or a micro short-circuit in a unit cell or group of cells of a fuel cell stack is provided by determining an electric output of the unit cell or group of cells after stoppage of fuel and/or oxidant and preferably during the introduction of a non-fuel and non-oxidant gas to the cell.
